Throwing out citizens because of some birth attribute they can not influence could be seen as inhumane. Would you think it's ok to throw out everybody with a certain eye color?
But then it needs to be defined what is local culture and what is foreign. And people would need to get the same treatment independently of their background. That is not what the AfD argues.
This point of view is seems actually widely represented in German politics

Ironically AfD leader is a lesbian married with immigrant Sri-lankian woman, so I doubt your claims.
